Merkel Cell Carcinoma: New Trends.

Cancers (Basel) 2021 Mar 31;13(7). Epub 2021 Mar 31.

Department of Radiation Oncology, Radboudumc, 6525GA Nijmegen, The Netherlands.

Merkel cell carcinoma (MCC) is a rare neuroendocrine tumor of the skin mainly seen in the elderly.

[Immuno oncology treatment in head and neck cancer].

Laryngorhinootologie 2021 04 30;100(4):303-321. Epub 2021 Mar 30.

In the near future, immunotherapy with checkpoint inhibitors will not only reach the relevant ENT clinics, but also the oncologically integrated ENT practice, since more and more patients under long-term therapy (currently up to 2 years) also have to be seen during clinical follow-up in the specialist practice. In this respect, we also consider as necessary that the basics of immuno-oncology in head and neck tumors are already taught as part of the ENT specialist training. In this review article, the background and the definitions of the therapy sections (first, second line treatment, marker, etc. Read More

Targeted literature review on use of tumor mutational burden status and programmed cell death ligand 1 expression to predict outcomes of checkpoint inhibitor treatment.

Diagn Pathol 2020 Jan 30;15(1). Epub 2020 Jan 30.

Pfizer, Inc., La Jolla, USA.

Background: To achieve optimal outcomes, an individual approach is needed in the treatment and care of patients. The potential value of tumor mutational burden (TMB) status and/or programmed cell death ligand 1 (PD-L1) expression as biomarkers to predict which patients are most likely to respond to checkpoint inhibitors has been explored in many studies. The goal of this targeted literature review is to identify data available for TMB status and/or PD-L1 expression that predict response to checkpoint inhibitors and/or anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) antibodies.

Advances in immunotherapy, most notably antibodies targeting the inhibitory immune receptors cytotoxic T-lymphocyte associated protein 4 (CTLA-4/CD152), programmed death protein 1 (PD-1/CD279) and programmed death-ligand 1 (PD-L1/B7H1/CD274) have become effective standard therapies in advanced malignancies including melanoma,1-4 merkel cell carcinoma5, urological cancers6-8, non-small cell lung cancer9-11, mis-match repair (MMR) deficient tumors12, and Hodgkin lymphoma with response rates ranging from 25 to 60% in the first and second line settings13,14. FDA approval has also been given for treatment for hepatocellular carcinoma, gastric cancer, triple negative breast cancer, cervical and head and neck cancers with response rates closer to 15 %15. Additionally, some clinical efficacy has been observed in ovarian cancer, mesothelioma, prostate cancer, diffuse large B cell lymphoma, follicular lymphoma, and both cutaneous and peripheral T-cell lymphoma.

Merkel Cell Carcinoma of the Head and Neck Compared to Other Anatomical Sites in a Real-World Setting: Importance of Surgical Therapy for Facial Tumors.

Facial Plast Surg 2020 Jun 30;36(3):249-254. Epub 2019 Dec 30.

Department of Dermatology, University Hospital Erlangen, Friedrich-Alexander-University Erlangen-Nürnberg (FAU), Erlangen, Germany.

Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine skin tumor with a high propensity for nodal involvement, local recurrence, and distant metastases. Up to 50% of MCC arises on head and neck (HN), which may impede oncological treatment due to insufficiently wide excisions and a lower rate of sentinel lymph node detection due to more complicated lymph drainage. Several studies have compared the clinical outcome of HN-MCC with those of non-head and neck (NHN) MCC yielding inconsistent results. Read More

Principles of prophylactic and therapeutic management of skin toxicity during treatment with checkpoint inhibitors.

Postepy Dermatol Alergol 2019 Aug 30;36(4):382-391. Epub 2019 Aug 30.

Department of Soft Tissue/Bone Sarcoma and Melanoma, Maria Skłodowska-Curie Institute - Oncology Center, Warsaw, Poland.

The introduction of immunotherapy into the treatment of cancer patients has revolutionised the oncological approach and significantly improved patient survival. The key drugs are immune checkpoint inhibitors (CPIs), whose mechanism of action is to elicit immune response against cancer cell antigens. Three types of CPIs are currently used and approved: an anti-CTLA-4 antibody, ipilimumab; anti-PD-1 antibodies, nivolumab and pembrolizumab; and anti-PD-L1 antibodies: atezolizumab, avelumab and durvalumab.
